Vibration

We supply a fully comprehensive range of pneumatic, electric and hydraulic vibratory equipment designed for use in a diverse range of applications which include assisting material flow from hoppers, feeding, screeding and compacting.

MVSI foot mounted electric external vibrators are widely used thoughout the concrete industry for assisting the discharge of sand and aggregates from storage and weigh hoppers also on vibrating tables for concrete compaction.

BV vibrators provide a cost effective solution on a wide variety of applications where noise is not a consideration, these include compacting and also material evacuation from bins and hoppers where bridging and rat-holing occur.

Available in a range of six models for single shot or continuous, hammer or air cushioned operation. Frequency / force controlled through air pressure adjustment.

Vibrating tables are manufactured in standard sizes to meet most requirements (other sizes available to order) including flat top tables type FTT and test cube tables type TCT.

Anti vibration mountings are incorporated in all models, their specification is calculated to ensure maximum isolation of vibration.

Tables are offered with cross members for location on clients concrete plinths alternatively floor fixing base frames are available. We also offer roller top tables and vibratory trestles to special order.

The DAR model pneumatic roller vibrators compliment our existing range of roller vibrators particularly for concrete applications. The design features, provide a more robust vibrator, suitable for use under the most arduous conditions.

The body is machined from an extruded aluminium section, inside of which a precision iron roller rotates in high tensile steel races. It is retained by two high impact special bronze end plates.

To obtain the best performance it is recommended that silencers of sintered bronze should be used to improve exhausting.

An air line filter and lubricator must be used to guarantee a long working life. Hydraulic oil ISO VG5 = 5cSt/40°C must be used, for example SHELL Tellus Oil R5.

Maximum temperature 200°C = 400°F.

Noise level range 75 to 100dBA.

Application

Model DAR high frequency pneumatic roller vibrators provide a new approach in the movement of fine materials. Being pneumatically powered, the frequency can be controlled by the regulation of air pressure.

Examples of their uses include:

•Compaction of plastic and concrete moulds
•Assisting the flow of material from chutes and hoppers
•Separation of various sizes of material on screens
